This is the original tank out of the boat. It is upside down.
This is the real cause of the problem. Holes on the backside where they were inaccessible and half way up so there was little usable tankage.
This is the shower sump after it was rebuilt it. Thru hulls were added for the AC drains and the two shower drains. The wiring is again some of Russ Smith's work.
The new 60 gallon tank in with supports. Like the fuel tanks, this tank comes down the companion way and in through the hatches. (A handle had to be added to make it easy to control.)
An ABI Tank Monitor was later added in the access plate with the display mounted in the forward head at the sink cabinet.
It is a bellows system so be sure to have the in the "empty" mode when the boat is laid up or the sensor will be frozen and unrepairable position.
The aft black hose is from the midship head and the forward black hose is from the forward head (where the shoes are). These hoses were replaced a couple of years ago to the new heavy duty hose
The finished floor with three not two hatches. The third hatch (forward) was cut from the existing floor, on the seams. Then the trim strips were added and the floor matches. The new cross members bolt in place much like the 1950/1960 stringer system of the Chris Craft's. They were sealed with West System for protection during wash down.
